Answer 1

在将react-native升级到0.49.5之后，我遇到了这个问题，我可以通过将我在android/app/build.gradle中对fresco的依赖更新为：

compile 'com.facebook.fresco:animated-base-support:1.3.0'
compile 'com.facebook.fresco:animated-gif:1.3.0'

这里是相关的主题，但与建议的1.0.1相比，似乎只有1.3.0起作用。

Answer 2

即使正确设置了multidex，我也遇到了同样的问题。

它为我做的是在app/build.gradle的android闭包中添加以下内容：

dexOptions {
    preDexLibraries = false
}
